EYEGLASS-HOLDER.

To all whom it may concern:

Be it known that I, FREDERICK R. BISHOP, a citizen of the United States,residing at North Attleboro, in the county of Bristol and State ofMassachusetts,y have invented a newand useful Improvement in Eyeglass-Holders, of which the following is a specification.

rllhis invention relates to certain new and useful improvements in eyeglass holders, and the object of the invention is to provide a noveltype of means for controlling and arresting the winding movement of thechain barrel when desired.

A further object of the invention is to improve, simplify and cheapenthe construction of devices of this type, in a manner hereinafter morefully pointed out and manifested.

In the drawingsv-Figure 1 is a front elevation of a device of thischaracter constructed in accordance with the present invention. Fig. 2is a rear elevation, Fig. 3 is a view similar to Fig. 1, showing thecover plate removed, Fig. 4 is a central vertical sectional view of Fig.2, Fig. 5 is a section of the base plate taken on the line 3 of Fig. 2,and Fig. G is a detached perspective View of one of the parts.

The invention as at present contemplated includes a housing whichconsists of a base plate 1 to which is secured by any suitable means acover plate 2. A fixed central hub 6 is provided which has its head 8formed with a cam-shaped stop 9, the hub or post 6 being rigidly affixedto the base plate 1 by means of a screw 7 shown in Fig. 4:. On the post6 there is mounted a chain barrel 3 which latter is rotated to wind upthe chain 11, by means of the spring 15, the latter bey ing connected tothe post and barrel whereby to revolve t-he latter. A pin 14 is affixedto the base plate 1 being secured to the latter by means of an elongatedstruck-up portion 13, the port-ion 13 being of U-shape in cross-sectionand being formed by striking or bending out a portion of the baseplate 1. The chain 11 carries at one end thereof the snap fastener 12 towhich latter the eye glass is affixed. A pair of diametrically oppositetubes or hollow guide members 4 are secured to or formed integral with,or in any other manner carried by one of the side faces of the barrel 3.Mounted within said Specification of Letters Patent.

guide members et are pins or detents 5 which have a free but true radialsliding movement in the guide members 4L, their outward movement beingrestricted by the annular shoulder 15 formed on the barrel 3. One end ofthe chain 11 is connected to the barrel and the opposite end thereof ispassed through the housing as at 16. The chain barrel 3, is formedmainly of a pair of abutting members each of disk form, the peripheriesof which are formed with L-shaped iianges, the two flanges coacting toform a U-shaped chain retaining part, it being understood that any formof chain barrel may be used, as this forms no part of my invention.

In operation it will be understood that the cam-shaped stop 9 in usenormally occupies the position shown in Fig. 3 of the drawing whereinsame points upwardly, the barrel 3 having an anti-clockwise movement,whereby as the pins or detents 5 reach a position where gravity acts onthe same to move them outwardly from the guide members 4;, they willfirst ride on the curved face of the cam-shaped stop 9 and on leavingthe latter will drop to the position shown in Figs. 3 and L1, engagingthe side face of the stop and arresting the rotary movement of thebarrel. It will be understood that the spring is wound so as to exertpressure on the barrel to move the latter in a clockwise direction, andconsequently one of the pins or detents 5 will be caused by the springto engage cam stop 9. In drawing the chain out it will be understoodthat the same moves the barrel in an anti-clockwise direction, in whichmovement the pins or detents ride on the curved face of the cam stop 9.The pins or detents return to their position in engagement with theshoulder 15, when the chain barrel operates with sufficient speed tothrow them centrifugally from the center. It will be understood that tocause the barrel to wind the chain up, when the latter is in itsoutermost position, merely fequires that the barrel be given a slightbut sharp anti-clockwise pull which will cause the detent in engagementwith the cam stop to be thrown outwardly, and the barrel thus being freeto revolve is given a rapid rotary motion effecting an instant windingup of the chain.

Having thus described my invention, I

claim as neuY and desire to secure by Letters Patent l. In an eye glassholder, a stationarily supported hub having a cam-shaped stop, a springpressed chain barrel rotatably mounted on the hub, a pair ofdiametrically opposed hollow guiding members carried by the chainbarrel, means slidingly arranged in said guiding members so as to have atrue radial movement With respect to the chain barrel adapted to havetheir inner ends engage With the cam-stop, and means to restrict theoutward movement of the said means.

Q. In combination with a base plate, a hub thereon, a cam stop carriedby the hub, a spring pressed chain barrel rotatably mounted on the hub,said barrel being formed With an annular shoulder, open-ended tubescarried by the chain barrel in diametrically opposite relation, saidannular shoulder closing the outer end of each of said tubes and a pinconformably andA slidably mounted in each of the tubes, said pins beingadapted to have their inner ends project beyond the inner ends of thetubes to engage with said cam stop.

3. In an eye glass holder, a stationarily supported hub provided with acam-shaped stop, a rotatable chain barrel surrounding the hub, aplurality of guiding means carried by the front side face of saidbarrel, said guiding means having their inner end portions locatedadjacent to said cam-shaped stop, a movable sliding element in each ofsaid guiding means, and means to engage said sliding elements torestrict the outward movements thereof.

In testimony whereof I have signed my name to this specification in thepresence oi two subscribing Witnesses.

FREDERICK R. BISHOP.
